16 Source Code Enhancements Overview Modification-free enhancement of source code Implicit Enhancement Option At common enhancement places, implicit Enhancement options are available. Examples: End of Executable Program, Include, Function group, Dialog module Begin/End of Form routine / Function module / Method End of a structure End of Private/Protected/Public Section of a local class... Explicit Enhancement Option Predefined enhancement options can be defined in source code. They are additionally stored inside Enhancement Spots.

22 Class/Interface Enhancements Class/Interface Enhancements allow for addition of: Optional parameters to existing methods Methods Events and event handlers References to interfaces Exits to existing methods Pre-Exit Called at the beginning of a method Post-Exit Called at the End of a method Overwrite-Exit Replaces the original method

23 Adding Methods & Parameters Adding new methods Adding optional parameters to existing methods

24 Pre/Post Exits Call method instance->hugo( ). Coding. Coding. Coding. Method Hugo. Endmethod. Method Pre.. Endmethod. Method Post... Endmethod.

25 BADIs - Overview What are BAdIs? Business Add-Ins Is an anticipated point of extension these points act like sockets and exist in the original coding Has a well-defined interface in contrast to source code plug-ins and is therefore more stable to changes in the original coding Kernel BAdIs - New Features Are integrated directly in the ABAP Language/Runtime Improved filter support allows non-character filter types (packed, numeric, string) and complex filter conditions Enable reusable implementation instances (Stateful BAdI) Control of the lifetime of implementations (BAdI-context) Allow for inheritance of implementations Can be switched by the Switch Framework

26 Comparison: Usage of Old BAdIs vs. New BAdIs With Classic BAdI DATA: bd TYPE REF TO if_intf. DATA: flt TYPE flt. CALL METHOD cl_exithandler=> get_instance EXPORTING exit_name = `BADI_NAME` CHANGING instance = bd. flt-lang = `D`. CALL METHOD bd->method EXPORTING x = 10 flt_val = flt. selecting implementations and issuing calls is mixed up calls cause DB access calls are redirected over a proxy class With New BAdI data bd type ref to badi_name. get badi bd filters lang = `D`. call badi bd->method exporting x = 10. selection occurs when the handle is requested no DB access during runtime Implementations are called directly (without a proxy) Active implementations are evaluated at compile time and included in the load of the BAdI-handle. Old BAdIs are more expensive than the new ones.

The migration can be automated. no special knowledge necessary effort: approximately 5 minutes per BAdI. SE18 -> Utilities -> Migrate ONLY when you have created Custom-BADI definitions in old systems

31 Performance Comparison Classic BAdI Migrated BAdI New BAdI x faster as classic BAdI x faster as classic BAdI 200%-2600% 4000%-60000% The more implementations are defined, the higher is the performance improvement

33 Switch Framework - Motivation Goal of the Switch Framework: Control visibility of repository objects at runtime through switches The Switch Framework can be used to Switch on industry solutions / Enterprise Add-ons Develop new functions without affecting existing ones Enhance delivered systems at partner and customer site in the context of the enhancement framework with own functions Benefits: Industry Solutions are available with every release and SP without delay (i.e. timely provision of legal requirements), CRT s* are no longer necessary for add-on systems Industry Solutions can be enriched by generic functions from other industries Synchronization of release cycles and planning * CRT Conflict Resolution Transport
